Trait glib::send_unique::SendUnique[−][src]

pub unsafe trait SendUnique: 'static {
    fn is_unique(&self) -> bool;
}
Expand description

Like Send but only if we have the unique reference to the object

Note that implementing this trait has to be done especially careful. It must only be implemented on types where the uniqueness of a reference can be determined, i.e. the reference count field is accessible, and it must only have references itself to other types that are Send. SendUnique is not enough for the other types unless uniqueness of all of them can be guaranteed, which is e.g. not the case if there’s a getter for them.
